The machine of theinvention'is des'ignedparticularly for soldering handlesfon cans, "and the machine will'be thus described-but with suitable modification thejnvention or parts thereof may 5 be applied to other-soldering operations; 1

Objects ofthe'inventio-n are to providea ma-- chinewhichis simple and compactand automatic and reliable in' its action, to provide a machine which is very economical inxthe, consumption of soldento provide a machine which requires; as little gas and air, or other fuel or energy;for--heating, as possible, to provide a machinewhich has I a large output and whichfcan be attended by one unskilledoperative, to provide a machinein' which there is no hazard to the attendant,'to provide a machine which requires no :compressedoair for cooling the handles or attachments after they are soldered to the bodies, to provide a machine which solders the attachments-to the canswith out danger of scorching or burning either the can body or the handle, ,to provide a machine in which the bodies are brought automaticallytothe soldering station, to provide a machine in which an attachment is carried to position for soldering only when there is a body to receive it, to'provide' a machinein which the solder, is fed .autoin'ati cally and in which thesolder; feedsonly when a body is present,'to provide a machine having a continuously moving conveyer'rwhich' advances the'bodies to the soldering station at intervals, to provide a machinehaving means for automatically ejecting the bodies after theattachments have been soldered to them, to provide a machinehave ing means for justifying the positions'zof the body and of the; attachment at the soldering station, and to provide a machine iwhich executes a neat and strong soldering job.

vThe invention comprises novel features and combinations making it possible torealize these objects. The can bodies are, brought successively to'a soldering station, where each can rests beneath orotherwise adjacenta soldering iheadi A means isprovided for introducing a handle at-.

tachment between thecan bodyand the soldering head. Mechanism then-produces relative movement between the can body and the soldering head, so thatthe can body and vthehandle, properly associated, are subjected to a soldering operation. This is preferably effected bypro viding a raising and lowering platform, on which the can'body is supported at the soldering station. Theattachment havingbeen soldered to Y the body, reverse relative movement between the body and, thesoldering head is" produced, pref- (erably by lowering the platform.) The can is then ejected or carried away fromthe soldering station by suitable means. s V Q m The term soldering head? is used in ,a general sense. In the most advantageous embodiment of the invention, the soldering head isone having irons to heat andmelt the solder without burn ing the can or the attachment, The relative movement-between the can body and the soldering I head, such as that obtained by raising theplat form, oauses the portions of, the handlewhich are l to besoldered to be clampedbetweenthe canbodyand the irons, this clampinginsuring afgood joint,

A further important provision is arneans to preventthe attachment from adhering to the irons, andthus to keep the freshly soldered joint from being broken or weakened, when thecaniand the irons are separated after thesoldering; Th-is is f accomplished by means of a resilient or equivalent 1 V yielding device which presses on the-soldered at- 'Ihe specific nature. of the means forintroducf 1 ing the attachment into positionbetweenthe can bodyand the soldering headmay be;yaried -'A simple and advantageous mechanism has been devised, consisting of areciprocatorycarrier hav ing jaws, one at least of whichis yieldinglypressed' towardthe other. This carrier advances at the proper time, clasps a; handleawaiting witg'pna ledge or support removed from thesolderingstation, and retreats so as to bring the' handleinto g position between the can-body and thesoldering I head. Then the can body is raised. Bythis relative movement, the body andv the handle" are 7 brought into contact, and thehandle. is brought into contact with theirons, one o'f thejaws ofthe attachment carrier yielding to this movementand holding the attachment inplace untiltheattachi *ment is held clamped between the, cans and; the

irons.- Then the ha'ndlecarrierretreatsiartherf,

and a spring presses on the handle toseparate the handle fromlthe irons after the soldering has beenaccomplished and when the relative move ment in the sense of lowering-the can: or raising the head is brought about. a 1

The invention also includes a, continuously moving conveyer for advancing the bodies to the 3 soldering station, this conveyer-havingpus'hers spacedapart a distance greaterthan the length" (lengthwise of'the conveyor) of the can bodies,

thus doing away with intermittently operated mechanism for the purpose.

Means are provided to prevent an attachment from being carried into position when there is no body. to receive the attachment.

' A means for feeding strip or wire solder is pro-j vided' for automatically supplying solder to the.

As illustratedinithe' drawings. this plat orm rhasibeen elevated, the handle "hasbeenpo-l sitioned on the can and soldering operation is aboutto lcomme'nce. As the can 'ismoved onto the platformiu, the platform is in it's lowered position or onthe same level as the stationary platformlfl and the can supports". 'Thefplatform 34 is provided with .a; 'fixedflange '35 and a spring-pressedshoe new act'as side supports for:thecan, the'spring pressed shoe compensating; for variations inthe widths :of the. cans.

positioning means.v f. Y

The handle carrying and .positioning'means comprises a reciprocating shaft45 having a rigid jaw 46 and a movable jaw 4L- The movable jaw 41 is pressed toward the fixed jaw,46iby springs 48 mounted on studs 49 passing through the movable jaw and threadedinto theyfixed jaw, thus providing means for-lightly butfirmly grasping the handle B; M j I The handle positioning meansis moved over to pick up'thehandle before the can has been raised by the platform 34. As soon as the jaws 46, 41, by their rearwardmovement, have moved the handle tothe-proper position over the can the platform 34 elevates the can. As the can rises [it contacts with; the. handle and raises the latter, bringing the ends or feet of the handle into contact with the irons 50,; hereinafter 'described. The ends of; the 1 handle are then clamped between the top of the can and the soldering irons 50. While the handle is raised as just described, thejaw- 4'! remains in contact with; the handle, since this ,jaw' can be raised against the pressure of theyielding springs 48. The handle positioning means then continues to move-back, away fromthe handle, and a spring finger 5| secured to the upper jaw rests on the handle B. Solder being fed-at the proper time by the. means later to be described-the handle issolderedto the body while the ends of the handle are clamped between the body and theirons. J: w 1

The spring 5| is-tokeep thehandle in position 'after it has been soldered and while. the solder hardens. When the soldering has. been completedIthe canis lowered, and. as the spring exerts .downward. pressure it will prevent; the endsofthe handle from adhering to the soldering iron 50; thus insuring that the freshly soldered connectionbetween the handle and'the body willnot be broken. i l v The shaft 45"ismou'ntedina guide 52 on a cross-member 53 carried by the standards 22.

The end of the shaft 45 opposite the jaws 4 6, 41 is connectedat 54 to a lever 55,'which is pivoted at 59130 a bracket secured to themain frame 2. The other end of lever 55 carries; a cam roller-5'1. which bears against a cam 58 mountedon the main driving shaft-l5. The

cam 58 is suitably formed tolcause the'handle positioning means to function as heretofore de 'scribed. A spring 60. holds the cam' roller 51 against thecam 58. The spring BOwill readily I give if the operator in placing a handle on" the ledge 43 should carelessly, allowv his fingers to come in contact with the 5 handle positioning means, and thus re ent injury to the operator.

Means are provided to prevent the handle positioning means from functioningunless a can isplaeed on the platform 34. A slide 6| is mounted .in guides formedin'abracket 62 secured'to the frame 2.

This slide will normally intercept the lever55- and act. as a stop to prevent. the 'lever operating the handle positioning means. .A' spring' 63 urges the slide 6| to this A link ispivoted to the slide and the opposite end: of. the link 64 is pivoted to a lever 65.

The lever 65 is pivo-ted at .68 to'a bracket. on the frame 2 andthef free vend ofthisleverlies in the path of travel'o-f the cans A. When a can is being advanced from position. b to position '0 it pushes't he free-end of the lever 65' and the slide ,6! is moved out of the path of lever 55,

' can.

thus lallowing .theihandle positioning meansilto function. If a can should be missingzinrthe regular succession of cans moved'throughgthe machine, the can inposition c would notbe ad vanced. Obviously,- there would then be no can.

in position: [1,; and it is most desirable that the handle positioning means can not function under suchconditions. There being no can to move'frompositionb to position c the free end of lever 65 would not have been displaced and the handle positioning means would not have operated. A stop '59 limits the'rearward move ment of lever 65.- u s "When the lever 65 visrpushed by one pfqthe cans; there is a slighttendency to overbalance I the can. To offset this a flexible finger 6'L-is movement. A;movable stop, 58 (Figs. 2.;and -3);'

prevents the can moving too far forward.-This stop as illustrated in thedrawings is almost in'its lower position. ,'It remains in the lower position until the can hasbeen ejected from A position d -and it is the n raisedto .,act as a sto'p' for the nextcan reaching this position. "A fixedfinger 69 acts as a guide at the upper :'part-:of t

the can.

- The stop 68 is in the form c-f a rod and its lower end is connected at 10 to a cam lever! I. The cam leverll is pivotedto'the frame at 12 and its free endbears'against the, cam.13 SGCHI'EdjtOLthB main driving shaft I5.

'At the soldering head, the so1dering irons 59 heretofore mentioned are securedto a horizontal bar 14, which is mounted in sockets formed uprights 15 secured to the standards 22'. V The bar is removably confined in the uprights l5 by'latches 16, which may be easily and quickly released for removing the soldering irons for cleaning purposes for applying the usual solu tions to aid the soldering operation. Guidesl-l Plates 18 may be securedto the soldering .irons for confining the heat and also toshield the operator. As illustrated, the soldering irons are heated by burners 19 provided with 'fueland air facilitate the insertion of thebar 14 in its sockets.

Means are providedfor feeding soldertothe soldering irons 5B. An-important feature ofthe I invention is a device whichinsures thatnosolder is fed tothe soldering irons 53 unless a can-is present under the irons.

The solder C in wire form is fed through tubes 8| suitably mounted on the standards .22 onithe cross-member 53, to apertures'82 .in' the soldering I It is passedflbetween 'grooved feedingf iron 50. rollers 83'and 84. Therollers 83 are mounted on a. shaft 85, which-is carried in brackets secured to'the standards 22. The rollers '84 are mounted on a shaft 81 carried in arms 88,-"which-i are pivoted at 89 to the brackets 86. springs illl' urgethe rollers 84 toward the rollers 83, so as" to provide a positive feed for the solder.

The shaft 85 also: carries ratchet s'lidabl-y mountedand guided in the frame l and standards. V a t i V Projections, 86 on rods 95 carry pins :or feelers Sl'whichrest on the tops of the cans, and also carry guidepin's 9 8 to prevent rods 95 from turn ing. Stop'coll'ars'99 are provided on the rods 95 to limittheir downwardmovement.

'When a'ca'n' is positioned ontheplatform 34 I and the'platform is elevated, thecanacting on the pins 91 will raise the rods95,causing the pawls 92, to advance the ratchets 9| several teeth, which in turn will rotate the feed rollers =83 and 84 a suiiicient distance to feed the required amount of solder for one operationwIf-no can is positioned on the platform, it follows that the vsolderC will not be fed; v V r ''-j.A bracket 400 secured to'the standardsil acts member 53 also function tofaid in positioning ards"?! steadies the-cans in position i I 1 After thehandle has been soldered onto'the cafithecan'may' be-ejected on a slide or chute 'I03or; it may pass directly onto a'suitable conxrv'eyer fen-carrying it to a Jtestingjmachine or othrf apparatus. 1
